Given that this style of circuitry used to be widely used in hideous coiled-wire sculpture lights favoured by elderly ladies, I do wonder how many got zapped by them before they switched to using low voltage light strings.
I really enjoyed reverse engineering this one. It's pleasingly functional for such a trashy design.
One update (more in the description on YouTube) the unit does NOT use phase angle control. It just pulse width modulates the LEDs on the unsmoothed DC.
